Curriculum Vitae

My research aims to make digital information space more accessible by designing effective human-computer interaction techniques. This means making it easy for people to achieve and manipulate information whenever and wherever. To make a whenever and wherever accessible interface, my researches mostly focus on designing an interface for mobile and wearable computing devices. My recent interest especially lies at utilizing gaze input modality to use rich contextual information which reflects on the user's eye gaze behavior.
